Fiscal Year calendar

Hi,

The SAP system runs with 2 co codes in production under the same controlling area. Now we want to add a new co code and separate controlling area but on the same production client - Same box. As annual clsoing works and production start up works are more it is decided to cut short the last period of production co codes by 2 weeks.

. To achieve that we want to close the year for the existing system 2 weeks ahead to have breather to take off the new co code on board.

Is it possible to reduce the exisitng Fiscal year - last period from 4 weeks to 2 weeks so that the transactions of th 2 weeks pushed to new fiscal year.

What i can think is the Fiscal year variant has to be different for the new and old co codes.( cant use the same)

Appreciate yr experience and thought process to get a resolution.

Thanks ,

Chitra
